Management and Policy Implications
Financially Mature, High-Value Stands
Predominate PAs forested landscape
Timber Availability is less than FIA Data Imply
Timber Industry Will Need to Adapt to
Species Like Red Maple
Recreation Value is Approximately Equal to Timber
Value in Many Areas
Methods to Project Current Conditions into the
Future Need to be Developed
Better Wildlife Habitat Models Would Help Gauge
Prospective Trends
Stand Rehabilitation will be Needed in Disturbed
stands with Poor Regeneration
Sustainable Forestry on Private Lands Needs
Assessed
Prepare Management Strategies for Late
Successional and Old Growth Stands
Strategies for Invasive Plants and Pests Need
Further Development

What We Cant Tell You Now
Only About 10 of Trees Remeasured the First Time
Through
Growth, Removals, and Mortality Are Not
Statistically Sound, Yet
We Will Remeasure More Trees This Season Than We
Did in the First Five Years!
